hashFiles is not defined

[ChloeCoupignyWarot]

I'm trying to get hash of a file but it doesn't work.

this is my code : hashFiles({"files":'/path/to/my/file', "algorithm":'sha256'}, function(error, hash){ if (error) throw error; console.log(hash); });

abd into server.js I added this : var hashFiles = require('hash-files');
